Installation for sorting mailings according to sorting directions
View Patent ↗Disclosed is an installation for sorting incoming mailings which are assigned to a first plurality of first preselected directions or a second plurality of second remaining sorting directions, according to which the mailings are distributed to receptacles of a track, each mailing being deposited into one of several first receptacles for the first plurality of first preselected sorting directions or into at least one of the other receptacles for the second plurality of second remaining sorting directions. At least one external receptacle from an additional track is replaced with a receptacle from one of the preselected first sorting directions of the track via an interface at least during one passage of the track, the additional track is used as a storage device for the receptacles, and replaced receptacles can be redirected to the respective track thereof via the interface.
1. An installation for sorting incoming mailings comprising:
a plurality of receptacles, wherein one group of receptacles is assigned a first sorting direction and another group of receptacles is assigned a second sorting direction;
a first receptacle track circulating a selected number of the receptacles from each group into which mailings are allocated based on sorting direction, the mailings received from a storage buffer in communication with a feeder track;
an external track circulating a remainder of receptacles not circulating on the first receptacle track which serves as a storage unit for the remainder of receptacles during at least one passage of the first receptacle track; and
an interface between the first receptacle track and the external track which is selectively activated to replace and return receptacles to their respective track by way of the interface thereby increasing or decreasing the selected number of the receptacles from each group on the first receptacle track in accordance with sorting direction requirements.
2. The installation as claimed in claim 1 , wherein both the first receptacle track and the external track have a total number of receptacles for predominant and remaining sorting directions, which are replaceable in pairs between the two tracks.
3. The installation as claimed in claim 2 , wherein the external track is a linear or ring storage unit.
4. The installation as claimed in claim 3 , wherein the interface is connected to a control module, which activates the interface as a function of actually occurring addresses or destinations of the mailings, which are random.
5. The installation as claimed in claim 4 , wherein the interface is connected to a control module that activates the interface with a periodic signal.
6. The installation as claimed in claim 5 , wherein the interface is connected to a control module that activates the interface with a sorting-direction-selective signal.
7. The installation as claimed in claim 6 , wherein the interface is connected to a control module that activates the interface as a function of a change in the throughput of incoming mailings.
8. The installation as claimed in claim 7 , wherein the interface is connected to a control module that activates the interface as a function of the individual pluralities of the sorting directions of incoming mailings.
9. A method of sorting incoming mailings in a mail sorting installation, comprising:
assigning a plurality of first receptacles to a first plurality of first preselected sorting directions in a first group;
assigning a plurality of further receptacles to a second plurality of second remaining sorting directions in a second group; and
assigning each of the incoming mailings to
a first plurality of first preselected sorting directions or
a second plurality of second remaining sorting directions, based on the receptacle that the mailing is deposited in,
circulating on a first receptacle track a selected number of the receptacles from each group into which mailings are allocated based on sorting direction, the mailings received from a storage buffer in communication with a feeder track;
circulating on an external track a remainder of receptacles not circulating on the first receptacle track, wherein the external track which serves as a storage unit for the remainder of receptacles;
selectively activating an interface between the first receptacle track and the external track wherein at least one receptacle from the external track is replaced with at least one receptacle from the first receptacle track during at least one passage of the track and the replaced receptacles are returned to their respective track by way of the interface thereby increasing or decreasing the selected number of the receptacles from each group on the first receptacle track in accordance with sorting direction requirements.
10. The method as claimed in claim 9 , wherein both the first receptacle track and the external track have a total number of receptacles for predominant and remaining sorting directions, which are replaceable in pairs between the two tracks.
11. The method as claimed in claim 10 , wherein the external track is a linear or ring storage unit.
12. The method as claimed in claim 11 , wherein the interface is connected to a control module, which activates the interface as a function of actually occurring addresses or destinations of the mailings, which are random.
13. The method as claimed in claim 12 , wherein the interface is connected to a control module that activates the interface with a periodic signal.
14. The method as claimed in claim 13 , wherein the interface is connected to a control module that activates the interface with a sorting-direction-selective signal.
15. The method as claimed in claim 14 , wherein the interface is connected to a control module that activates the interface as a function of a change in the throughput of incoming mailings.
16. The method as claimed in claim 15 , wherein the interface is connected to a control module that activates the interface as a function of the individual pluralities of the sorting directions of incoming mailings.
